ENSILAGE-COMPRESSOR.

etitia.

To all whom it may concern:

Be it known that T, JOHN F. T'IARRISON, Jr., a citizen of the United States, residing at Mexico, in the county of Audrain, State of Missouri, have invented certain new and useful Improvements in EnsilageCompressore; and Ido hereby declare the following to be a full, clear, and exact descriptlon of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.

This invention relates to ensilage compressors or packers, and has particular reference to a mechanism for packing down ensllage in silos. i

The invention has for its object to provide an improved mechanism for evenlypacklng the material which is filled into a silo around the inner wall of the silo as well as in the center, a particular mechanism being pro vided for controlling the packing element.

With the above objects in view and such other objects as will hereinafter appear my invention will now be fully set forth and described, reference being had to the accompanying drawings.

In the drawings Figure 1 is a vertical section through a silo showing my invention in operative form,

Fig. 2 is a side elevation of the machine for raising the weight,

Fig. 3 is an enlarged detail v1ew of a traveler or carriage employed as a part of the invention,

Fig. 4: is an enlarged detail view of the weight adjusting mechanism, and

Fig. 5 is a further detail view.

Referring more particularly to the drawings 1 represents the wall of a silo which is surmounted by a number of beams 2, the latter meeting in an apex over the middle of the silo. At their apex, the beams 2 are provided with a bearing in which is vertically slidable a hanger 3 whose lower end has swiveled thereto a pulley block 45. The upper end of the hanger is provided with a coil spring 5, the upper end of the hanger be ng threaded to receive a head for the spring and the opposite end of the latter being rested against the bearing. The upper end of the beams 2 are clamped by means of the bolts 6, and brackets 7 carried by the lower ends of the beams 2 clamp the beam structure to the upper edge of the silo wall. One

of the brackets 7 carries a standard 8 upon which 1s mounted the yoke 9 in which a pair of guide pulleys 1O revolve. The pulleys 10 and the block l provide a means for guiding a cable 11 into the S110. The inner end of the 11 by means of an adjusting cable 16 which is passed a suitable number of times over the pulleys 13 and 14, the latter being doubled or tripled as the particular construction requires. A latch 17 upon the block 12 provides a means for locking the end of the ca ble 16 at any desired position of adjustment. Surrounding the inner face of the wall 1 near its upper edge is an endless trackway 18 which consists of a tubular structure, as an iron pipe and is carried upon the L- shaped brackets 19 in such relation that substantially the whole peripheral surface of the tubular trackway is free to provide a continuous bearing forthe travel of a carriage 20. The carriage 20 consists of a substantially split ring structure which carries at its ends, the conical rollers 21 which bear upon the under surface of the tubular trackway 18 and the roller 22 which rides upon the top of the trackway. Upon its inner side, the carriage 20 is provided with an offset in which is mounted the multiple pulley 23. The multiple pulley 23 cooperates with a corresponding pulley 2% in carrying a cable 25. The pulley 21 is carried by a block 26 through which the cable .11 passes and is therein guided by means of a roller or pulley 27. The carriage 20, the block 26 and the cable 25 provide a means for varying the distance between the tamper 15 and the wall of the silo, the operator standing within the silo and drawing up the cable 25 until the approach of the block 26 to the carriage 20 has positioned the tamper.

The outer end of the cable extends to the ground or to the other suitable point where the actuating mechanism is located. The latter consists of a base 28 upon which is rotatably mounted a comparatively large disk 29. Said disk is connected by means of a belt 30 to a suitable power source, preferably, the ensilage cutter driving mechanism. Upon one face of the disk 29 is provided the roller 31 which is positioned to strike against and carry for a certain distance the trip lever 32, to which the outer end of the cable 11 is secured as in the coupling 33 carried by the triplever The oute'r end of'the trip lever 32 is pivoted in "a standard 34;,

and its upward movement is limited by a stop 35 which consists of a verticalstandard having its upward end overturned to impress the-trip '1ev'er'32, so that the'l'atter is pulled upwardly by the tamping weight of the roller 31 as passed out of engagement with the trip lever, the latter will not fly wildly around its fulcrum. V

The operation of the mechanism is ap- 15 parent from the foregoing description, but

it should be noted that the mechanism is so mounted that the tamper may be easily swung from one locality to another within the silo with little effort, the operator pulling up or letting out on the cable in order to position the tamper'15 radially, and shoving the carriage 20 around the trackway 18 in order to position the weight circumferentially. In this way without difficulty,

5 the weight may bebrought to operative positionover any point within the silo, By meansof the cable 16, the immediate adjustments which are required to meet the rise of the ensilage in the silo may be met. When further vertical. compensation is necessary the outer end of the cable 11 is adjusted in the coupling -33 upon the trip lever 32. The

coil spring support for the hanger 3 pro-' Vides ameans for taking up the ar and vi- 35 brations caused by the rise and fall of the tamper.

1. An ensilage packing mechanism, comprising in combination, a tamper, flexible means for suspendingsaid tamper froma central-point, means -for actuating the suspended means to operate the tamper, a carri'age'movable around the central point, and a connection between said carriage and the tamper suspending means for bending the latter to vary the distance of the tamper from the carriage.

2. An ensilage packing mechanism, comprising in combination, a tamper, means for suspending the tamper centrally in a silo, a trackway around the inside of the silo, a carriage operative over said trackway, a pulley surrounding said tamper suspending means and means connecting said pulley to the carriage for varying the distance'between the tamper and the side of the silo.

3. An ensilage packing mechanism, comprising in combination,a tampena means for resiliently suspending the tamper cen five cents each, by addressing the Commissioner of latents.
